Reproduces the algorithmic cost of the historical Markdown::append
(`SharedString::new(s.to_string() + t)` per chunk) against the new
buffered path on a 60 KB / 100 x 600 B fixture matching the streaming
shape observed in downstream consumers.
cargo bench -p markdown --bench append_throughput on a Ryzen 7 7800X3D:
pre_fix_concat/60kb_100x600b ~94 us
post_fix_buffered/60kb_100x600b ~2.4 us
ratio ~38x
The criterion HTML report under target/criterion/markdown_append/ is
the load-bearing artefact for the perf claim.
